Abstract

Abstract: In the hinterland longitudinal dunes of the Taklimakan Desert, in order to explore the differences of dust horizontal flux and grain size characteristics of the near-surface in dust weather, we use BSNE samplers to gather sand-dust of different heights within 80 meters above the surface in the fall of 2014. The results show that the horizontal sand-dust flux of the near-surface is neither in power function distribution nor exponential function distribution during dust weather processes due to the influence of the compound longitudinal dunes. It decreases with the height below 20meters, while increases with the height of 24-63 meters, and 24m and 63m are the turning points. The mean particle size of each layer is between 64-80μm, dominated by very fine sand. The sorting coefficient is between 0.96-1.12, belonging to general sorting. The grain size frequency curve shows double peaks in the distribution. The main peak appears between 80-110μm, the second peak in 10-20μm. Multi peak reflects the complexity of the dust composition. Remote dust in each layer changes small, the major sand are local and regional sources. The variety of dust horizontal flux and grain size suggests that the leading wind speed and direction, strong rising motion and longitudinal dunes are the main reasons to the vertical differences.

Key words: Taklimakan Desert, dust horizontal flux, grain size
